Natural Products in Regression and Slowing of Progression of Atherosclerosis
Bibliographic record
Abstract
Many natural products, including vitamin E, garlic, purpurogallin, flaxseed and its components [secoisolariciresinol diglucoside (SDG) and flax lignan complex (FLC)] and resveratrol have been reported to suppress hypercholesterolemic atherosclerosis. It is known that all of the drugs that suppress the development of atherosclerosis do not regress and/or slow the progression of atherosclerosis. To be of potential benefit in patients with established atherosclerosis, a drug should produce regression and/or slow the progression of atherosclerosis. In this review, the effects of vitamin E, SDG and FLC in the regression and slowing of progression of hypercholesterolemic atherosclerosis and their mechanisms have been described. The effectiveness of vitamin E in patients with established coronary disease is very controversial. However, in experimental animal controlled studies, vitamin E does not regress or slow the progression of hypercholesterolemic atherosclerosis. The mechanisms of the ineffectiveness of vitamin E in regression and slowing of progression of atherosclerosis have been discussed. SDG is effective in slowing the progression of atherosclerosis and partially effective in regression of hypercholesterolemic atherosclerosis. These effects are associated with reduction in oxidative stress. FLC does not regress hypercholesterolemic atherosclerosis but slows the progression of hypercholesterolemic atherosclerosis. Slowing of progression is associated with reduction on oxidative stress. In conclusion, vitamin E does not regress or slow the progression of established atherosclerosis. SDG slows the progression and regresses established atherosclerosis. FLC does not regress but slows the progression of established atherosclerosis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
